TITLE: Aluminum’s Energy Revolution: How One Startup Is Turning Scrap Metal Into Industrial Fuel
The Aluminum Energy Breakthrough
In a Boston laboratory surrounded by pipes and wires, Peter Godart and his team at Found Energy are preparing for what could be the most significant real-world test of aluminum as a zero-carbon fuel. The startup has developed technology that rapidly releases energy from aluminum scraps to power industrial processes without fossil fuels. After years of small-scale development, the company has now activated what it claims is the largest aluminum-water reactor ever built.

Early next year, this revolutionary system will be installed at a tool manufacturing facility in the southeastern United States, where it will supply both heat and hydrogen using the plant’s own aluminum waste as fuel. This installation represents a critical milestone in proving whether aluminum can serve as a practical, carbon-free energy source for heavy industry.
Why Aluminum as Fuel?
Engineers have long been intrigued by aluminum’s potential as an energy source due to its remarkable energy density. Once refined from ore, aluminum metal contains more than twice as much energy as diesel fuel by volume and nearly eight times as much as hydrogen gas. The fundamental chemistry is straightforward: when aluminum reacts with oxygen from water or air, it forms aluminum oxides while releasing substantial heat and hydrogen gas—both valuable energy carriers., as related article, according to market trends
Godart explains the appeal: “We invented the fuel, which is a blessing and a curse. It’s a huge opportunity for us, but it also means we do have to develop all of the systems around us. We’re redefining what even is an engine.”, according to industry analysis
The Historical Challenge
The primary obstacle that has frustrated previous attempts to use aluminum as fuel is what Godart calls the “self-passivating” nature of the metal. When aluminum begins to react with water, it immediately forms a protective oxidized layer that prevents further reaction—much like a fire that generates its own ash to smother itself., according to industry news
This challenge has led many experts to dismiss aluminum as a practical fuel. Geoff Scamans, a metallurgist at Brunel University London who spent a decade working on aluminum-powered vehicles in the 1980s, remains skeptical: “This potential use of aluminum crops up every few years and has no possibility of success even if aluminum scrap is used as the fuel source.” He argues that the aluminum-water reaction isn’t efficient enough to justify the substantial energy required to produce aluminum from ore initially.
Found Energy’s Catalytic Breakthrough
What sets Found Energy’s approach apart is a fundamental rethinking of catalysis. Rather than trying to speed up the reaction by bringing water and aluminum together on a catalyst surface, the company “flipped it around” and developed a liquid metal catalyst that dissolves into the aluminum itself.
Godart describes the innovation: “The real breakthrough was thinking about catalysis in a different way. We found a material that we could actually dissolve into the aluminum.” This catalyst permeates the aluminum’s microstructure, causing the metal to froth and split open as it reacts with water, continuously exposing fresh, unreacted aluminum to sustain the reaction.
Industrial Applications and Impact
The technology’s potential extends far beyond the initial manufacturing facility installation. Industries that require high-temperature heat—such as cement production, metal refining, and chemical manufacturing—represent particularly promising applications. These sectors account for substantial greenhouse gas emissions and have proven difficult to decarbonize through electrification alone.
The aluminum-powered system offers multiple energy outputs:
- High-grade heat for industrial processes
- Hydrogen gas that can be used for additional power or chemical processes
- Aluminum oxide byproducts that can potentially be recycled back into aluminum production
The Road Ahead
The upcoming installation at the tool manufacturing facility will serve as the most comprehensive real-world test of aluminum as an industrial fuel to date. Success could transform how industries view both their energy sources and their waste streams, creating a circular economy where aluminum scrap becomes valuable fuel rather than waste.
While skeptics like Scamans maintain that “a crazy idea is always a crazy idea,” Godart and his team are betting that their catalytic breakthrough has finally solved the fundamental challenges that have thwarted previous attempts. The coming year will determine whether aluminum’s time as a zero-carbon fuel has finally arrived—or whether it remains a promising concept awaiting its practical solution.
As industries worldwide struggle to decarbonize, the success of Found Energy’s approach could provide a crucial tool for reducing emissions in sectors where alternatives remain limited. The experiment beginning early next year may well determine whether aluminum joins hydrogen, batteries, and biofuels as a viable pathway to a zero-carbon industrial future.
